. The disturbance continued to gradually become better organized through the following day, and although it still lacked a well-defined center of circulation, the threat of tropical storm-force winds along the southwestern coast of Mexico prompted the initiation of advisories on Potential Tropical Cyclone Sixteen-E at 15:00 UTC on September 28. Early on the following day, the disturbance's circulation became better defined, and an increase in convective banding occurred over the western portion of the broad system. As a result, the NHC classified the system as Tropical Storm Narda at 03:00 UTC on September 29. Moving slowly northward toward the southern coast of Mexico, Narda gradually became better organized and strengthened to an initial peak intensity with winds of 45 mph (75 km/h) as banding features became evident. However, later that day, satellite imagery and radar data from coastal stations in Mexico indicated that the center of Narda relocated further north and close to the coast of Mexico near

. Microwave imagery revealed the presence of well-defined banding features and a mid-level eye feature located just off the Mexican coast, and Narda reached its peak intensity with maximum sustained winds of 50 mph (85 km/h) at 21:00 UTC on September 30.

Narda continued to weaken as it hugged the northwestern coast of Mexico, and by 12:00 UTC on October 1 it had weakened to a tropical depression while just off the coast.
